I have recently installed Ubuntu 10.10 on my Dell Inspiron n5010 but screen brightness is not working, there is no effect of pressing fn+brightness keys.
Is there anyway to fix it?
I just updated the BIOS and now brightness is working great.
You may have to choose Dell Inspiron as your keyboard layout in the keyboard section of Administration. I had to do this with my Fujitsu Seimens Lappy.
Maybe this laptop has the same problem as my Acer Aspire 4736Z.
These solutions might help you:
Such shortcuts are handled by the
udev subsystem. The configuration files exist in /lib/udev/.
The way it works is that you add a description of your laptop in /lib/udev/keymaps, and then activate it for your laptop in /lib/udev/rules.d/. There is more to the description I provide. You would need to read how similar laptop variants are handled already to get your laptop supported.
I also have have Dell Inspiron N5010 model, Brightness settings works fine for me with Ubuntu 10.10 64bit. You dont need to press fn key to adjust the brightness.
